Question:
My camera displays the following „At low voltage it is difficult
to obtain night video. / It is difficult to obtain night video under
low voltage." What does this mean?
When the camera is turned on, the message „It is difficult to obtain
night video under low voltage" appears, indicating that the battery
is very low. If the battery voltage is lower than 4.0 V, the infrared
light cannot be switched on. The camera cannot take pictures or
record videos at night. The power consumption of the infrared light
is very high and exceeds normal power consumption. It is recom-
mended to set the video length shorter or as needed during the
day. The camera does not need to switch on the infrared light and
can still record videos.
